Asus ROG G700 (2025) (Ultra 9 285K / RTX 5080 / 32GB RAM / 2TB SSD)

Manufacturer: Asus

The Asus ROG G700 (2025) is a desktop gaming PC configured with Intel's Core Ultra 9 285K processor and NVIDIA's GeForce RTX 5080 graphics card. Built in an ATX form factor, it targets users who need a high-specification desktop system, and its 32GB of DDR5 RAM provides a solid memory foundation for demanding workloads and gaming sessions alike.

On the graphics side, the RTX 5080 is based on NVIDIA's Blackwell architecture and carries 16GB of GDDR7 VRAM across a 256-bit memory bus, delivering a maximum memory bandwidth of 960 GB/s and 56.34 TFLOPS of floating-point performance. The CPU operates with 24 threads across a hybrid big.LITTLE configuration, reaches a turbo frequency of 5.7GHz, and is paired with a Z890 chipset on an LGA 1851 socket. Connectivity options include Wi-Fi 6E, Bluetooth, two HDMI 2.1b outputs, four DisplayPort outputs, and an assortment of USB ports spanning USB 2.0, USB 3.2 Gen 1, and one USB 3.2 Gen 2 Type-C.

Pros
  • The RTX 5080 GPU delivers 56.34 TFLOPS of floating-point performance with 16GB of GDDR7 VRAM and 960 GB/s memory bandwidth, making it well-suited for demanding rendering and gaming workloads
  • The hybrid CPU configuration spans 24 threads across 8 high-frequency and 16 efficiency cores, reaching a turbo speed of 5.7GHz with an unlocked multiplier for overclocking flexibility
  • Four DisplayPort outputs and two HDMI 2.1b ports allow connection of up to four displays simultaneously
  • Wi-Fi 6E support alongside a wired RJ45 port gives flexible networking options for both low-latency cabled connections and modern wireless use
  • The system supports up to 128GB of ECC RAM across two channels at speeds up to 6400 MHz, providing substantial headroom for memory-intensive workloads
  • A 2TB NVMe SSD provides generous fast storage capacity for large game libraries and application installs
Cons
  • At 510mm tall, 421mm deep, and 185mm wide, the chassis occupies a considerable amount of physical space that may not suit compact setups
  • The 360W CPU TDP places significant demands on cooling and power delivery infrastructure
  • No Thunderbolt 3 or Thunderbolt 4 ports are present, limiting compatibility with high-bandwidth Thunderbolt peripherals and external devices
  • Air-water cooling is not included, so thermal management depends entirely on whatever solution is separately provided
  • With only 32GB of RAM installed despite the platform supporting up to 128GB, the memory configuration leaves a large portion of the platform's capacity unused out of the box
Who is this for?

This system is well-matched for users who run demanding gaming and GPU-intensive workloads, given the RTX 5080's 56.34 TFLOPS, 16GB of GDDR7 VRAM, and full ray tracing and DLSS support. The 24-thread hybrid CPU with an unlocked multiplier and a 5.7GHz turbo also makes it a capable platform for content creators and developers who rely on multi-threaded processing alongside heavy graphics tasks. Those who need a multi-monitor desktop setup will find the combination of four DisplayPort outputs and two HDMI 2.1b ports particularly practical, with support for up to four simultaneous displays.

Who is this NOT for?

The chassis dimensions — 510mm tall and 421mm deep — make this a poor fit for users working within space-constrained environments, as the physical footprint is substantial even by full-tower ATX standards. The absence of Thunderbolt 3 or Thunderbolt 4 ports means users who depend on high-bandwidth Thunderbolt peripherals such as external GPUs, high-speed storage arrays, or professional audio interfaces will find connectivity limited. Additionally, the 360W CPU TDP and the lack of an included cooling solution make this unsuitable for anyone seeking a low-maintenance or acoustically quiet system without investing separately in an appropriate thermal setup.

Final Verdict

The Asus ROG G700 (2025) in its Ultra 9 285K and RTX 5080 configuration is a full-sized ATX desktop built around a clear set of priorities: raw computational throughput, graphics capability, and multi-display flexibility. The RTX 5080's 56.34 TFLOPS of floating-point performance paired with 16GB of GDDR7 VRAM positions it firmly as a system designed for users who push hardware consistently hard, whether through intensive gaming, GPU-accelerated creative work, or complex rendering tasks. Its platform-level headroom — ECC memory support, up to 128GB RAM capacity, an unlocked CPU multiplier, and a Z890 chipset — suggests it can grow with demanding workloads over time. That said, its large physical footprint, 360W CPU TDP, and the absence of Thunderbolt connectivity mean it asks something of its environment and its user in return. For those who can accommodate it, the ROG G700 (2025) represents a comprehensively specified desktop that leaves little on the table in terms of processing and graphics capability.
